Description
This application is a divisional of application Ser. No. 09/932,818, filed Aug. 17, 2001 now abandoned, which is incorporated herein by reference.
The present invention relates to a fluid treatment device and, more particularly, to a water filter system having a plurality of selective filter usage counter mechanisms for monitoring the number of uses of the replaceable filter cartridge and including a color coding element for visual inspection to permit the user to determine the status of the filter.
Fluid treatment devices are known and used in homes for removing contaminants from normal tap water. Since the filters fail to perform after many successive uses, an indicator must be visible and readable to the user to permit the user to determine when to replace a filter.
Duncan, U.S. Pat. No. 5,190,643; Gebhard, U.S. Pat. No. 6,033,557; Tanner, U.S. Pat. No. 5,882,507; Lund, U.S. Pat. No. 5,785,844; Hofman, U.S. Pat. No. 6,074,550; Huang et al., U.S. Pat. No. 5,873,995; Levene, U.S. Pat. No. 5,665,224; Lund, U.S. Pat. No. 5,536,394 and Bailey, U.S. Pat. No. 6,001,249 all pertain to filter systems with an indicator to tell when the filters needs to be replaced. Such devices include float mechanisms, rachet and pawl mechanisms and the like.
It is an object of this invention to provide a device for fluid treatment which will enable the user to determine at any time the status of the filter by color coding. A further object of this invention is to provide a fluid filter usage indicating mechanism which will permit the consumer to change the cycle depending upon the statutory usage required in various countries around the world where replacement filters must be changed according to existing regulations which are known to vary from country to country.
Yet another object of this invention is to provide a unit which is readily assembled and will not dislodge, tilt, come apart or disintegrate under adverse conditions.
Still a further object of this invention is to provide a filter unit in which color coding is used which will not scratch or bleed off during use or washing. This is particularly true where dishwashers are used which might cause the color dyes on the system to be washed away or otherwise destroyed.
Yet another object of this invention is to provide fluid treatment mechanisms which will fully drain all liquid from the assembly after it is immersed and washed.
Yet another object of this invention is to provide a filter cartridge mechanism which will operate when the cap is replaced regardless of the orientation of the placement.
Another object of this invention is to provide a fluid filter mechanism which will have a minimum useful life of at least 3,000 cycles at one filter change setting or 7,000 cycles at another filter change setting depending upon the country of use thus permitting up to approximately 9.6 years of use if the product is used twice a day.
Yet a further object of this invention is to permit the replacement mechanism to indicate when the filter cartridge must be replaced when the amount of water discharged through the cartridges is at least about 80% of the approved capacity of the cartridges.
Still a further object of this invention is to provide a fluid filter mechanism which cannot be disassembled except by destruction of the item, thus avoiding accidental loosening of parts which might fall off during washing or other uses.
Yet another object of this invention is to permit the counter mechanism to accurately count the number of times the container has been filled.
In summary, this invention relates to a fluid treatment and filter counter mechanism which monitors the number of uses of the filter cartridge indicating when it must be replaced, such as by, for example, color coding. The counter mechanism also includes a plurality of selective filter counter mechanisms depending upon the requirements of a particular country.
It will be appreciated that relative terms such as left, right, up, down, clockwise, and counterclockwise are for convenience only and are not intended to be limiting.
These objects and summary will be understood from a detailed reading of the following description including the drawings which are as follows:
In the embodiment shown, the removable and replaceable cap C has a generally elliptical shape. The device D includes a pouring spout P which is formed and extends along one side thereof and a handle H on the opposite side thereof. A lip 2 is formed on the removable and replaceable inner lid Z. A window W located on the removable and replaceable cap C for viewing a painted consumer indicator dial is subsequently described.
The chassis 10 comprises a gear and ratchet plate 12 and pawl follower 14 and a hub 16. The gear and ratchet plate 12 is secured to the hub 16 by a lock washer 36 or a nut or other fastener. The gear and ratchet plate 12 includes gear teeth 18, a plurality of ratchet wheels 20 and 22, a slot 24, a stop 25 and color indicator 26 (FIG. 5 ). A return spring 28 engages with the gear teeth 18 causing the gear teeth 18 to go counterclockwise. The follower 14 can be set at the large diameter ratchet wheel 20 or can be set at the smaller diameter 22, depending on the filter cycle used.
It is possible to provide more concentric ratchet wheels than the two shown and additional slots in the opening 76. The return arm 40 is provided with an opening 82 and mounted on the spindle 38 extending to the gear and ratchet plate 12. The return arm 40 exits from the chassis cover 70 and an opening 84 and is secured by lock washer 36. Cover chassis 70 has a view sleeve 86 with window W. The cover chassis 70 is locked by means of snap members 88 to the chassis. Hub handle 16 is rotated in order to reset the gear and ratchet plate 12. Each time the chassis 10 and its assembly are indexed the selective ratchet wheel 20 or 22 causes the color coding indicator 26 on the gear and ratchet plate 12 to be exposed to the window W. As will be noted in FIGS. 5 , 9, and 11, color runs from green in the lighter area G to the darker yellow Y to darkest area red J, thus indicating to the consumer the status of the filter in the device D. Holes 90 mounted with bolt 92 keep the chassis cover on cap C tight.
In the operation of the fluid treatment device D, the hub 16 is rotated substantially until the green color indicates at the window W. This begins the sequence of operation of the ratchet and pawl mechanism 20 and 22 depending on which one is used. The pin 74 shifts from position 78 to position 80 in order changes the gearing counter mechanism.
While this invention has been described as having preferred design, it is understood that it capable of further modification, uses and/or adaptations following in general the principle of the invention and including such departures from the present disclosure as come within known or customary practice in art to which the invention pertains, and as may be applied to the essential features set forth, and fall within the scope of the invention or the limits of the appended claims.
